$ SMALL mass minus BiG mass is NEGATiVE mass $
EARTth mass - Sun mass = NEGATiVE mass, duh.!!
PROOF: Delta mass = 1*kg - 2*kg = - 1*kg .!!
G~FORCE FRAME of REFERENCE:
G*M1*m1 / r1^2 = m1*(n - 1)*v1^2 / r1.!!
The GUESS *SiGNETiC* mass, mS = (n - 1)*m1 .!!
Where n = Cavity of m1 DisCHARGE mass mD / m1.
MORE mass MAY be DisCHARGED, from a CAViTY of
TEST mass m1 than all the mass of m1, itself.!
VERY sincerely u c,
